Be itglmown that I, C ARLES SULFER, a citizen of'the United States, anda resident of the city of Chicago, county of Cook, and State ofIllinois, have invented certainnew and useful Improvements inTotal-Adding Cash-Registers; and I do hereby declare that the followingis a full, clear, and exact description of the same, reference'being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

. 'This invention relates to improvements in cash registers and moreparticularly to a cash'register of that 'class adapted to be operatedwithout the use of lever keys. Ofthe many cash registers heretoforedevised most have been provided with levers, whereby the operator, bypressing upon the appropriate lever actuates mechanism for recording theamount of the transaction. With all such registers continued use servesto put the register levers or keys out of alinement and'it sometimeshappens that a dishonest employee may be able to make the machine recordincorrectly for that reason, and owing to the use of levers and themultiplicity of parts, it is not uncommon for such registers, when outof order, to record incorrectly at times without the knowledge of theoperator, making it impossible to determine with certainty the-result ofthe days business.

With thisin view, the object of this invention is to provide a cashregister operated wholly by means of rotary elements and by dials eachappropriated to a single denomination of the money to be counted.

It isalso an object of the invention to provide in a device of the classdescribed, rotary mechanism for recording the transacr tion' orpurchase, and simultaneously exhibitiing in a suitable view aperture, avisible sig- I na they occur, and in which the-{registering}\rnechanisrncah be setback tolO, very qu ckly...

It is an important object "of the invention also toaflo' fdinconnection-with mechanism of theiclass described, a totaladdingiregister,

which,-howso'ever the dials are operated, cannot falsify the record,each dial operating 111- H enlarged dependently to insure an accuratecount and I the dials for lower denominations carrying the countautomatically to those of a higher denomination. i" i i The inventionembraces many novel fea- 6.0

As shown in the drawings: The mechanism is mounted upon a base A andwithin a removable casing A beneath which is the usual or any suitablemoney drawer A and is supported within a frame consisting of end platesa and a, which are rigidly secured to the base plate A. J ournaledcentrally on said end frame members and supported upon suitablebearings, is a shaft B,

which protrudes through the front frame plate a, and is provided thereonwith a dial B, having marked thereon at equal distances apart andapproximately in a semi-circle near its periphery, the numerals andsigns $1, $2, $3, $4, and $5, reading from the bottom upward. f courseany desired number ofv dollars up to and including nine dollars may beindicated thereon.

As shown a standard B is supported on the base and affords a support forthe end of said shaft B. The shaft Bis journaled near its middle portionon an upright or standard I), supported on the base-plate A, as shown inFig. 4. Rotatively mounted on said shaft concentric therewith andextending inwardly thereon, from the front end, is a tubular shaft C,having a dial C thereon, similar to the .dial B, and rotative around thesame and marked consecutively on approximately half its periphery toindicate dimes'from 10 cents to 90 cents, in elusive, and mounted torotate on said shaft C, is an outer tubular shaft D, having a dial D,rigidly secured thereon, and marked from 1 to 9 inclusive on asemi-circle to indicate pennies. Said dial, is shaped to fit around thedialC, and all the dials are arranged with their faces in the samevertinea'th the numeral 1 on the dial D" and at the same distancetherefrom, as the nu"- merals from'each other is marked No sale. Asshown said numerals on each dial are marked upon a circular button (1secured in suitable sockets in the dials and which are made of cast, orpressed metal, or any material suitable for the purpose, and a spring01', shown in Fig. 36, normally holds the other face of said buttonflush with the face of the dial but permits the same to be pushedlnwardly to enable the finger to engage in the socket to rotate thedial.

Rigidly secured on the shafts B, C and D are cams or wheels, such asshown in Fig. 12, and indicated as a whole by B C, and D, for therespective shafts, these, as shown, are each provided with a singleangular tooth b"- cd. The number of said cams on each shaft .is the sameas the number of stations on its dial, in other distances apart inapproximately a semicircumeference to correspond with the arrangementof. the numerals on the dial. Said cams are spaced a slight distanceapart on the shaft, by means of a relatively thin plate a of metalengaged between adjacent cams, as shown in Fig. 4, and which are rigidlysecured on their shafts by keys or by a projection suitably positionedwith central bore in one of which w is shown in Fig. 12. They are'alsosecured in place by means of nuts d"'ic -b, threaded on the respectiveshafts and between which and the cams, on each shaft is rigidly secureda gear-wheel b-c-d*.

Rigidly secured to the front and rear frame plates ar- -a' by means ofits downwardly bent ends H", as shown in Figs. 5, 6 and 16," is a rigidhorizontal bar E which is positioned at the left of and above the dialshafts, and a central depending bracket c is secured at about the middlethereof and, extending through said bracket and the end e of said bar,is a non;rotative shaft Pivoted on said shaft e between the bracket cand the end bracket e are inwardly directed arms c -e, which extend tonear and above said gears on said dial shafts, and are connectedintermediate their ends by a rigid horizontal bar E on which just at therear of the gears d and b are secured inwardiy directed rigid arms E.These are in length equal to the projection of the arm e beyond the barE and each is provided with a downwardly directed spring controlled pawle, at its extremity positioned to be engaged by a cam e secured on therear side of each gear wheel, on each dial shaft, and which acts to liftall said arms simultaneously. Also secured on said shaft e andprojecting forwardly over the bar E are relatively broad leaf mit thearms to swing upwardly against the tension of the spring.

Hinged on the base plate A opposite each set of cam wheels is a standardshown'more, plainly in Figs. 8 to 11 inclusive. This, as shown,comprises a projection or boss f, rigidly secured to the base plate, andon the top of which is hinged a tubular body F, as

shown in Fig. 11, in which is slidably engaged a cylindric and threadedstem f, held from turning therein by means of a'pin f, secured in saidstem and extending into a longitudinal slot,

blade or plate f having its upper edge i of the leaf spring 6.

is provided near said end on its under side.

directed horizontally and longitudinally of the machine and rounded toafford a support, and of a length to extend across the face or .edge' ofall the cam wheels in the set oppositewhich it is secured. Supported attheir inner ends on the upper rounded edge 7" of said hinged supports,are transversely slidable pawl bars G, which equal in number the cams ineach set and are positioned respectively directly above each of the camwheels. Each is provided at itsinner' extremity with anupwardly directedprojection or tooth 9, adapted to engage beneath and behind the downturned lip or detent e As shown also each with a notch having downwardlyand outwardly inclined sides toward the adjacent end of the bar, and theother side therof affords a somewhat rounded shoulder 9 Directly aboveeach cam wheel a downwardly extending tooth g is provided on each pawlbar, adapted to be engaged only by the tooth on the corresponding camwheeh As shown also said pawl bars betwen the tooth on each, and theshoulder g are cut away to afiord an inclined face. for engagement bythe teeth on the cams as the same are rotated forwardly thereby liftingthe ends of the pawl bars. At its opposite end, said pawl bar ispivotally engagedand supported upon a lever G, the upper end of whichprojects above the top plate a As shown also a comb 9 is secured beneaththe top plate, and the teeth thereof extends downwardly between the saidpawl bars, holding the same positioned each directly above its actuatingcam.

Arranged obliquely on the upper side of the top plate as shown in Fig.2, is a set of bell cranks H, ten in number corresponding with the 1number of cams on the penny shaft, D, and rods 72/, connects theforwardly directed arms h, with the upper end of the lever G, beforedescribed. The opposite arm 71;, which is directed transversely themachine, is pivota'lly engagedby a rod k which leads rearwardly,-and 1sadjust ablyconnected with a downwardly directed arm h, of a lever hwhich is pivotally supported at the rear "end of the frame, 1 as in saidtubular body. Said stem is ad usted as to height by meansof a nut f andjam nut f,

- out contact.

ated pawl bar. passes beneath the spring shown in Fig. 4 Saidleversextend forwardlythrough a vertical comb h, and are each'p-rovided at itsforward end, with an upwardly directed arm 71.", on the upper end ofwhich is a tablet 72?, which may be as shown of circular or any desiredor suitable form and on the front and rear faces of which there ismarked or indicated the numeral, sign or other representation orrepresentations contained upon the button of the -dial from which saidpawl arm is actuated. 'There are, of course, as many of said levers asthere are stations on all the three dials including the No sale station.In-

asmuch as ten of said levers are appropriated to penny dial, nine to thedime dial and five to the dollar dial, there are also necessarily ten ofsaid bell cranks in the series'H,

for pennies, nine in the series H for dimes and five in the series H fordollars, each of which when actuated by its pawl bar acts to elevate theproper tablet to afiord a visible signal in the viewaperture A, at thetop of 'thecase. Inasmuch. as the tooth on the cam, correspondin meralon the dial 1t is'desired to record, is directly in front of the toothg" onthe pawl bar said teeth on the cams engage and successively liftthe pawl bars, against the tension of their springs g", shown in Figs. 6and 16, until he completion of the forward movement or count ofthe dial.When the dial is released at the end'of the forward movement, the toothd 'c orb on the cam, corresponding with the count to be represented andwhich has just'passed and is )ust in position with the nuj in advance ofthe tooth g on the corresponding pawl bar, immediately engages saidtooth g as the dial returns to its normal position, and said pawl bar ismoved lengthwise pushing the hinged support F, therewith and therebyelevating the adjacent ends of the remaining pawl bars, (owing to theinclined surface of the notch in said pawl bars in which the top of thesupport rests) to a height to let the remaining teeth on said cams passbeneath, with- The end of the positively actuplate '6, to be retained,elevating its tablet into view, until a dial is again actuated when thecam e engages the pawl 6 end of one of the arms 6 or E lifting the onthe same and releasing the pawl bar'andpefi mitting the visible signal'to fall Of course any suitable mechanism may be provided to return thedials and'cams to position for the next count. For th s purpose,

to said standards i, are strong coiled springs i, which are wound up byrotation of the withthe gears d*.0*b* reand securedto the axle or shaftfor each said gear, and

respective dial shafts when actuated by their dials, and act to quicklyreturn the dial actuated to normal when released. v As shown in Fig. 16means are provided to insure the dial always stopping at normal. Forthis purpose a stop 5 which may be integral with the cam projection e isrigidly secured on the dial shaft gear b*-c and engages the top of theappropriate standard mwhen the dial is, at normal. In the same mannerthe opposite end of said stop or any suitable stops may be provided onsaid gears to engage the standard 2' or any suitable rigid part of themachine, to limit the 5 downward movement of'the dial when actuated tomake its'maximum count. As

shown, both said stops and the cam projec tion a", are formed fromsingle plates of the proper 'size and shape rigidly secured on the rearside of each gear. The return .movement of the dial, and cams under theaction of said springs, is also regulated to prevent pounding or injuryto the machine. For this purpose a governor is provided comprising ashaft J, journaled on suitable standards J'J'* secured on the base plateA and gears 7' are rotatively securedthereon in-mesh with the positivelydriven gears I, for each dial. As shown in Figs. 6 and 28, a disk 7', isrigidly secured on each gear j and bearing against the face of said'disk is a ratchet 7' rigidly secured on said shaft J, and which isengaged by a spring controlled pawl 7' on said disk' 'j', therebyrotating the governor shaft J, as the dial returns to position. )n therear end of said governor shaft J, is secured a ear 7' which meshes witha pinion j, secure "on the. same shaft with a gear 7', which in turnmeshes 40 with a pinion 7',- which drives a centrifugal governor J ofany suitable kind, and which is provided at one end ,withia frictionbrake wheel 7' adaptedto be en aged by ashoe 7', as shown in Fig. 5.-aid governor is of'the dials when .any one or more of the dials areactuated and acts to retard the re- Y turn movement'of the dialtoprevent shock due to .violent impact of the stops 2?, on the 0standards iflthough' of course if neces'sa said governor may be drlvenwhen the dials are rotating in either or both directions.

Means are provided for making an audible signal and to unlock the moneydrawer simultaneously with the actuation of the dial. For thisi'gpurposea pivoted spring pressed finger is, secured on each of the gears. bc dand project beyond the periphery thereof sufliciently to engage arms is,secured on a'shaft k, which extends lon= "gitudinally of the machinebeneath the top plate a, and through the rear frameplate a as shown inFig. 7. At the rear side of the end plate a, a bar-la isrigidlysecuredatits middle on the shaftk', and on one end of the bell, and as the barreturns to'normal en.-

obviously driven .on the return movement longer period is provided. F orthis -pursame is provided a strong pulling spring is,

which acts .to hpld said end firmly down upon a stop la Apad which maybe, of

rubber or 'other suitable material is secured on the end gf said bar toabsorb the'shock of the returirbfsaid bar to normal position afteractuation. A bell K. is secured on said frame plate a, and a hammer 7a.,is secured on a spring rod lo, iii-position to strike said bell whenactuated. As shown also a depe'ndin'g hooked arm is is pivotally engaged.on said end of said bar F, in position to engagethe protruding end ofthe spring rod k, beyond: the hammer ;and lift the same and av springis, is engaged on said arm and acts to hold the same normally inward inposition to engage said hammer rod. "A stop 1 k is secured on said frameplatetolimit the inward swing of said arm 71", under the action of itsspring, and the inner side of the arm is so shaped that when the" bar Kreturns to normal the hooked end of the arm, is", swings beneath andengages the hammer so that rotation of said shaft It. acts first torelease the hammer, sound the signal on the ga ed the hammer on the arm70'.
